To Adjust The Blade Tension
Turn the Blade Tension Knob (245) clockwise to
increase tension on the Saw Blade (251). Turn the
Knob counterclockwise to decrease tension on the
Saw Blade. Correct tension is acquired when the
Saw Blade does not slip on the Drive and Idler wheels
(231S and 250S). (See Figure D and Figure C.)
NOTE:
When the Bandsaw is not in use over long
periods of time, release the tension on the Saw Blade.

To Adjust The Blade Guide Bearings
IMpORTANT:
Blade Guide Bearings (266-10)
adjustment is a critical factor in the performance
of the Bandsaw. Replace the Saw Blade (251)
to see if it will correct poor cutting quality before
adjusting the Blade Guide Bearings. For example,
if a Saw Blade becomes dull on one side sooner
than the other, it will begin cutting crooked.
Replacing the Saw Blade will correct this problem,
but adjusting the Blade Guide Bearings will not.
1. If a new Saw Blade does not correct the problem,
check the clearance between the Saw Blade and
Blade Guide Bearings to obtain proper clearance.
There should only be a maximum of 0.001 clearance
between the Saw Blade and Blade Guide Bearing.
To obtain this clearance, adjust as follows:
2. The Blade Guide Bearings (266-10) are
mounted to the Guide Pivot Assemblies (270S)
and can be adjusted. (See Figure E.)
3. Loosen the Hex Socket Head Screw (269-9)
while holding the Guide Pivot Assembly
with a hex key (not included).
4. Position the Guide Pivot Assembly by turning
it to the desired position of clearance. Then
re-tighten the Hex Head Socket Screw.
5. Adjust the second Blade Guide
Bearing in the same manner.
